' to one temple, that shown being the right hand 3 Claims.

This invention pertains to fly shuttle looms and more particularlyrelates to selvage devices therefor. 7 It is the general practice inweaving cloth to add extra ends in the selvage to carry the strain orjerk of the filling as the shuttle is picked across to the opposite sideof the loom. To eliminate thenec essity of such extra ends in theselvage, loom selvage devices are employed. Such devices usually includea needle or loop retaining member placed in the warp adjacent theselvage to take up the aforementioned strain or jerk of the filling.When the reed moves forwa'rdly to beat the'newly laid filling into thecloth, the needle or loop retaining device must be ra'med from the warpand moved to an out of the way position.

Accordingly it is a principal object of this invention to provide in aloom having a lay, a shuttle guard rail and a temple, at selvage devicecomprising a supporting member adapted to be secured to the temple andhaving a guideway therein, a movable needle carrying member mounted onthe supporting member and having a projection thereon for engaging theguideway, the projection and guideway being so constructed and arrangedas to provide for movement of the needle in an arc in a vertical planewhereby the needle will be raised from the warp and moved forwardly toan inoperative position.

This and other objects may be accomplished in the constructionillustrated on the accompanying drawing, of which:

Fig. 1 is a plan view of a portion of a loom showing the right handtemple with my invention mounted thereon;

Fig. 2 is a side view of the device of my invention showing the needlein its operative position;

Fig. 3 is a view similar to that of Fig. 2 but showing the needle in itsforward inoperative position; and

Fig. 4 is a View taken on line 4-4 of Fig. 1.

As the present invention relates only to a particular feature in theconstruction and operation of the loom it is considered sufficient toillustrate and describe only those parts of the loom directly concernedwith a preferred embodiment of the invention.

A usual type of temple l, a portion of the lay 2, shuttle guard rail 3and the warp threads 4 are shown in their usual relation.

The device of my invention is adapted to be attached to loom temples. Asthe construction is generally similar at both sides of the loom on thesupporting member I.

it is sufficient only to show the device as attached ineedle bar I I.

temple.

The device may comprise an attaching and supporting member having anattaching portion 5 secured to the temple 1 by means of bolt 6 and asupporting member 7. Supporting member 7 extends longitudinally of theloomand has a laterally projecting pin 8 and a rearwardly upwardlyinclined elongated slot or guideway 9.

A reciprocatory member 10 is slidably mounted The reciprocatory memberin has a laterally extending needle bar il adjustably. mounted on itsrear end and an upstanding hunter [2 adjustably mounted on its forwardend. A set screw l3 locks the needle bar in adjusted position. Lock nutsl4 lock the hunter in adjusted position. A single needle or a pluralityof needles 15 are fixedly attached to Reciprocatory member lil hasintermediate its ends a laterally extending pin it and a forwardlyinclined elongated slot or guideway H. The pin 8 extending from thesupporting member 1 engages in slot ll in the reciprocatory member if!while the pin it extending from the reciprocatory member Ill engages inthe slot 9 in the supporting member l'. The pin and slot connections actas cam means for guiding the movement of member Iii.

A coiled spring l8 has one end attached to pin 8 and the other endattached to pin it. Spring I8 acts to hold reciprocatory member It inits rear position. When the reciprocatory member is in itsrear'position, pin 8 is at the forward end of slot I7 and pin it is atthe rear end of slot 9. Upon forward movement of reciprocatory memberif) the pin 8 engaging in slot i1 guides the movement of the rear end ofmember it and pin it engaging in slot 5; guides themcvement of theforward end of member Ill. The two slots are so disposed in angularrelation to each other as to cause the rear end of member if] to travelthrough an arcuate path, the first part of the movement of the rear endof member iii being substantially vertical and then changing into asubstantially horizontal movement.

The operation of the'device is as follows:

On the rearward beat of the lay, spring 18 moves reciprocatory member l0rearwardly, thereby moving the needles I5 downwardly into operativeposition in engagement with the warp. On the forward beat of the lay,shuttle guard rail 3 engages the hunter l2 and moves reciprocatorymember I U forwardly, thereby raising the needles [5 from the warp andmoving them through an arc forwardly and upwardly to inoperativeposition where they will not interfere with the reed.

The needles when in operative position in engagement with the warp takethe strain or jerk of the filling as the shuttle is picked across to theopposite side of the loom. It should be noted that the needle bar II isadjustable laterally of the warp, this adjustment is provided so thatthe needles may be positioned to produce a loop selvage.

Having thus fully disclosed the preferred embodiment of my invention, Iclaim:

1. In a selvage device for a fly shuttle loom including a lay having ashuttle guard rail mounted thereon, the combination of a supportingmember having a guideway therein, a movable member slidably mounted onsaid supporting member for movement longitudinally of the loom, saidmovable member having a needle adjustably mounted on its rear end and aprojection intermediate its ends for engagement with said guideway, saidguideway and said projection being so constructed and arranged as toguide said movable member through an arc in a vertical plane, anadjustable bunter mounted on the forward end of said movable membensaidbunter being adapted to be engaged by said shuttle guard rail for movingsaid movable member in one direction and resilient means for moving saidmovable member in the opposite direction.

2. A loom selvage device comprising a supporting member having aprojectionat one end and a guideway at the other end, a needle carryingmember slidably mounted on said supporting member and having a guidewayadjacent one end and a projection adjacent the other end, saidprojection on said supporting member engaging in said guideway in saidneedle carrying memberand said projection on said needle carrying memberengaging in said guideway on said supporting member whereby uponmovement of said needle carrying member said needle will be movedthrough an arc in a vertical plane.

3. A selvage device for a loom including a lay and a shuttle guard rail,said device comprising a supporting member having a laterally extendingprojection adjacent one end and a downwardly inclined guideway adjacentthe other end, a movable member having a laterally extending projectionadjacent one end and an upwardly inclined guideway adjacent the otherend, a needle mounted on the rear end of said movable member, saidprojection on said supporting member engaging in said guideway on saidmovable member and said projection on said movable member engaging insaid guideway on said supporting member whereby upon movement of saidmovable member said needle will be moved through an arc in a verticalplane, a hunter adjustably connected to the forward end of said movablemember, said bunter being adapted to be engaged by said guard rail onthe forward beat of the lay for moving said movable member forward, acoiled spring connected at one end to said movable member and at theother end to said supporting member for moving said movable memberrearward.
